by mesne assignments, to Waterbury "Button Company,

a corporation of Connecticut A Appiication september 4, 1940, serial No. 355,399. s ff 3 Claims.

The present invention relates to improvements in siphons and more particularly to that .class of Siphon which is mounted upon the neck of a bottle containing carbonated water, soda or the like for the purpose of maintaining the gas pressure in said bottle or container and having an automatically closablevalve assembly subject to manual opening whenever Ythe contents of said bottle is to be `dispensed or decanted; particularly aresiphons of `this type used in connection with the delivery of carbonated liquid under pressure for use'in mixing such beverages as Whisky and soda.

Among others, the important objects oi the invention are to simplify the construction, both interior and exterior, of such Siphon devices and to promote the economicaland expeditious manufacture of the same, toA enable the quick and economical assembly of the separately manufactured parts, to promote ready. mounting of the device upon the bottle neck, the effective seal of the container against the escape o f Ythe gas, and in general to .improve the use of the device particularly in; the act of opening the valve to dispense the contents. V

Other objects of the invention are to improve the appearance of Siphon devices as tments for modern commercial bottles, to provide improved valve assemblies for the same, to improve the devices for binding these tments upon the bottle neck, and to so construct and arran-ge the external contours of the siphon head as to lead the hand and the fingers inpercepti-bly and guidingly to the button or head'whch-'operates the valve assembly and to enable the depressing of said head or button in a facile and quick manner.

An important object of the invention is to so construct and arrange the interior ofthe siphon head as to provide in a structure of requisite lightness and sufcient strength the various internal parts to receive and cooperate with the valve assembly and nozzle and to enable sockets to be formed in the head for the trunnions of the fastening bail. i Y

A stillfurther object o1 Vthe invention is in the Siphon tube and its veldable head with its improved method of mounting.

With the foregoing and other objects in View,

Vthe invention will be hereinafter more fully described and more particularly pointed out in the appended claims.

A tV I5 is represented Athe siphon tube carried by a pressible material and'projecting down into y,the bottle with itslower portion near to the lbottom of said bottle. l .y

As shown more particularly. in Figures l and 2 the Yrubber block has afcylindrical external conformation -compleinental to in the lower wider base portion of the siphon This cylinder opens out through'the lower basfe portion of the Siphon head I4,f'At its upper end the cylinder IlV ends abruptly against fa shoulder i3, vwhich connues the upper end lof' the block i6 and arrests the 'upward or inward motion of block 'ii into the lower open. end of compressed, and intliis fsiphon head I4. Y

Normally the block I6 will have,'when' uncom-` pressed, a greater external diameter than the intern'al"diameter` of cylinder Il.' VIn'order to insert block It into cylinderi I 'I the block must be slightly compressed condition forced into the cylindrical opening Il 'and against theshoulder I8.'` l,

Below the cylindricalv partof block I6 isthe block I6 of rubberor 4otherfsuitable coma'cylinder Il formed vforced up through leading ed'geof allyH from 'fwith the upper' end ,of aba'rrelV 26.

oiffsrnallerl external diameter 'than the internal `rlf-hdsalt -its upper 'end a ,21 of the dome. At its lower end itbpensffreely "into 'the iiiteriial'chamber' 2 annular seat I9 conforming generally to the form of the interior mouth of the container I2 into which it accurately and sealingly rits. Below the seat I9 the shank of the block E extends into the bottle mouth and may be beveled oi as indicated at 2B, the bevel running generally from the seat I8 to the sipho-n tube I5. This Siphon tube I5 is `a. central opening 2I in the blockY IS, such central opening 2l being normally initially smaller than the external diameter of the tube I5, whereby the rubber of the block will have to be expanded or crowded out along the the inherently resilient rubberof the block IB,

to admit the tube I5 which causing such block to tightly embrace and'susL tain the tube I5. This tube I5 is urged upwardly in block I6 to a point where the upper end of the tube I5 terminates short of the open upper end of the opening 2l.k This leaves a narrow neck 22 of rubber or other resilient material of which the block I6 yis Inadeprotruding inwardly of 'the tube I5 to overlap the upper end or such tube substantially the thickness' of the wall 'ofthe tube I5 so that the narrow free neckA 22 does not encroaoh 'upon the cross sectional varea of the tube I5 in any manner vto impede or lobstruct the flow of the contents of the bottle through such tube I5 and opening 2l into the hollow chamber of the head Jill. At the same time thenarrow 'Y free neck 22 marks a zone transversely completely across the upper part or" blocli'i where the rubber is not c r'owdedlout by theA presence of ltube VI5. For thisQreaso-nthe outer upper edge o block I6 `Withinthe confines of the'iree -lip 22 may bemore easily compressedinwardly, and the rubber generally in this upper Zone of the block lism'ore amenable to contraction.v This Zone forms the the block` i5 when inserted in the cylinder] Iand the'freedom of this Zone is therefore of'importanc'e in facilitating the insertion of Asuch'leading edge' of the block'IG into theCYlinder i1. Gnce the'leading edge is worked into'the lowerfpartoA cylinderv I`1 the remainder ofjthe Lcylindrical portion of the block I S' may bercrovvded radially inward against tube vI5 by a'camming incident to the thrust of the .block I6 upwardly into the siphonjhead.v The radial crowding o f the bloei; rubber concentrically outward otube'l increases the resilient action for binding the block I6 in the Siphon head. A strong binding action of block i6 bothupon thesiphon head and yupon the tube l5 'is important Vas the block I6 is depended Vupon to support the tube I5.

lxternally of the cylinder .I4k is formed with a number of annular beads 23 `whichserve as grips for the ngers at'the end Yp ion ofthe head in the act of mounting the 'merit'up'onv the neck I2 of the bottle or` other "conteiner.`

innerhalb/"the head' I4 is generally @hind-Cal,

The valve 29 is supported upon a stem 3S and hasa beveled upper face SI for seating against the lower end of the barrelA 2e, lthe valve 23 being preierablyci a block of rubber sov thatits bevel ilaeehseats"jhtlyagainst the sharp vinnular corner at the 1 ner lower edge or" the barrel 2E.

of the wire or rod are shaped to provide the arms and the trunnions. vItV will be noted yfrom Figures 1 and 2 particularly that the vbail meinberv 56 is flattened in a horizontal sense. Due to this iiat vertical cross section as compared with the horizontal cross section the bail member 59 will be subject to vertical distortion. This ability is enhanced by the support of the bail member 53 solely at its ends by thearms 48 and 49.V YBe-Y cause the bail member issubstantially semi'- circular and because of its lack of support throughout its entire arc and because of the flat'- wise construction and inherent resiliency it will yield or distort opposed by such resiliency thus' causing the bail member to bind very tightly beneath the lip I3. As shown in Figure 1 the trunnions lie in line with the vertical -aXis ol the Siphon head but so as to move to the right of this vertical vaxis line. As shown in Figure 13 the curved arms `43 and 49 joint with outwardly flared parts 5I and 52 which form the leading edges ofthe bail and which in the downward swinging movement of the bail first encounter the neck of the bottle I2. These flaring jaws thus guide the semi-circularV bail on to theneck the arms 43 and 49are-bent` and beneath lip I3. In Fig- `whenever necessary. In the samemanner ther ure l the bail is shown as in home position.

Without the presence of the liprI3 the bail member 55 would incline from the lower ends of the arms upwardly to the ber slips under the neck it is caused to tilt down springingly about the lower ends of the arms and thus put the bail member andthe arms underV tension which tension serves to retain the bail member in its fastening positionand causes the bail member to draw the head I4 down tightly upon the block I 6 thus compressing the block' as to its seat I9 upon the neck of the bottle- `This act also tends to lit at this point. n Y

Referring more particularly to Figure 4, the block of rubber forming valve 29 is formed with a socket 53 open at its top but closed at its bottom and adapted to tightly hug the lowerA end of valve stem SQ overwhich it is removably mounted. Y

As shown in Figures l and 5 the lower part of cross-sectionally rounded valve stem 30 is squeezed out into a cruciform construction V(Figure 5) so that projecting flanges 54 and 55 eX- tend in opposite directions and are wider in their combined diametric length than the original diameter of Valve stem 30 so as t0 DIOJ'SCIJ HallOW parts into and embed themselves into the rubber of the valve body 29 thus interposing large rsurfaces against the casual rotation of the valve body 29 with respect to valve stem 30 and offering Wide and large obstacles to the accidental movement of the valve body 29 downwardly or off the valve stem 30.

Referring more particularly to Figure 11, a modied form of valve assembly is shown con'- sisting of the stem 56 to the upper end of which is welded or otherwise aiiixed the concavoconvex cap 51 beneath which engages the coil spring 58. The valve stem 55 is threadedat its.

lower end 59 in order that there may be run thereon an internally threaded sleeve 60 the outer surface 6I of which is knurled to receive the The rubber of the valve body 62 will tightly embrace Ythe knurlings of the sleeve S0.'

In the use of the device, the coil spring reacting against Washer left but as the bail mem-v jam the leading edge of 'block I 5 against shoulder I8 formingra tight sealing 34 and septum '33 will automatically at all times.v

Yjoins theA solid formation web and at the bottom, as shown in Figure 1,1 such Web slopes down inthe generaldirection o of the diagonal spout 24.

tend to lift the operating button or vcap 36, thus lifting with it the valvefstemand'the valve 29, closing the latter against its seat atthe bottom of thebarrel 26. {This-,condition obtains place on a bottle as shown in Figures 1, 2`and.7,

leakage of gasfwillbe completely prevented by the rubber block I6 and by this closed position of the Valve 29. Obviously bythe arrangements shown in Figures 4 and '11 the rubber valve `bodies 29 and 62 may be removed and renewed block I6 may be renewed when required.

lWith the parts in place the user may simply up through the tube vI5 and outthe barrel `as the pressure is released from the button or operating member 36 the helices of spring 35 willvv expand upwardly land automatically close the valve`29. z

vA hollow web 53Y integral with the material of the head I4 extends at right angles from the barrel 2liA over to the the opening of the .delivery spout 24. This web Z'I at the top of the vThe head I4. may be of Bakelite, or of any of the new synthetic resins or other compositions such as to enable it t0 be molded cheaply. In view of this the internal arrangement of the head I4 is adaptable to molding and at the same time is calculated to produce strength in a molded Varticle from a plasticA of thisI kind.

The peculiar formation 'of thethree Webs extending 1n spacedannular relation to one another andextencling at approximately degrees apart at one side lof the circle of the Siphon head and at degrees at'the other side provides :a Siphon head Vthat is substantially hollow and of light Weight and economical construction While thev requisite strength and reinforcement is imparted through the solid dome head and from the side walls through the webs to the barrel Vto preserve the alignment of the barrel in its relation to the reciprocating valve; although slight misalign-Y ment is compensated for by thelarge rubber body .of 'the valve 29. In other words the bulk of the Valve permits it to accommodate itself yto seats, the positions of whichvary somewhat' in manufacture.
